Customer Reviews
Great shower filter
I got the Shower Filter and it's fantastic! The water felt so much softer right away, and my skin feels better. Installation was super easy, took like five minutes. I'm definitely going to get one for the other bathroom!
Good filters, customer service helped
I ordered some Replacement Filter Cartridges for my under sink system last month. They shipped out pretty quickly, but one of the cartridges was the wrong size when it arrived in Denver, took 6 days to get here. I called customer service and they were actually quite helpful. They sorted it out and sent the correct one right away, which was nice. The filters themselves are good quality, fit just right once I got the correct one, and the water tastes clean. It was a bit of a hassle with the wrong part, but they fixed it, so I'm happy enough with the overall experience.
Whole house system install went well
We bought a Whole House Water Filter System a few weeks ago. It got here pretty fast, like 4 days, then I had a plumber set it up. Everything seems to be working good since then, water tastes fine and no issues yet. It was a decent price too, especially for a whole house setup. Felt good about the purchase.

Hey, wondering how often I'd actually need to swap out filters on one of their whole house systems? Seems like a hassle if it's super frequent.
